Description

Stage lighting system and method for providing high-brightness white light

FIELD OF THE INVENTION The present invention relates to functional features of lighting devices or systems thereof, in particular lighting systems mainly used for stage lighting.

Background technology LED (Light Emitting Diode) light source is a green, pollution-free, clean and energy-saving light source, and its achievable luminous flux design index is increasing year by year. At present, LED light sources are mainly used in some low-power, low-end color-changing lamp products.

High-power stage lighting sources mainly use metal halide discharge bulbs. The metal halide discharge bulb is a white light source, and its service life is relatively low, generally ranging from hundreds of hours to thousands of hours. Because the emission spectrum of the metal halide discharge bulb is a white continuous spectrum, the different colors required by the stage lighting can only be achieved by filtering with color filters, so that the patterns projected by the lights have low color saturation and the colors are not bright. , nor rich. In order to improve the color saturation of monochromatic light, a filter with extremely narrow bandwidth can be used to filter the light. The disadvantage is that it will reduce the brightness of monochromatic light.

If the stage lighting adopts LED light source, the color filter can be omitted, and the color of the light source can be changed by adjusting the current of different primary color LEDs, so that the higher color saturation of the single-color LED can be used to make the color of the stage light more stable. The degree of freedom of expression is greatly improved. But at present, LED generates a lot of heat, and its luminous efficiency is not high enough, and a single LED chip cannot withstand high power. Therefore, the high luminous flux of high-power stage lighting is often achieved by LED arrays.

The Chinese patent with the application number 200720061982.0 discloses a light source assembly for a stage light, which uses an LED array and a large cooling device, can provide a luminous power of 100 watts, and can control the work of different colored LEDs in the LED array. Implement color adjustments. Its shortcoming is: based on performance indicators such as heat dissipation and luminous flux, especially the consideration of the uniformity of bright color of the output light, this light source module cannot meet the needs of high-power stage lighting.

For this reason, the company has proposed in the Chinese patent application that the monochromatic light from multiple LED arrays is synthesized into one beam through a light splitting and color combining device, which can increase the output power of the light source and improve the uniformity of light output brightness.

The disadvantage of the prior art of using LED arrays in the above-mentioned stage lighting system is that the luminous efficiency of the system is lower than that of the traditional metal halide discharge bulb solution when white light is produced. The efficiency of the light source is hardly affected by heat, so whether the output power of the light source is high or low, the efficiency of the output light is almost unchanged. Taking the existing 575-watt moving head light as an example, the luminous flux output by the bulb reaches 49,000 lumens, and the luminous efficiency is 85 lumens/watt; while the luminous flux output of the 1200-watt moving head light reaches 110,000 lumens, the luminous efficiency is still 85 lumens/watt . Correspondingly, when a high-power LED light source uses monochromatic light to combine light to produce white light, the electro-optic conversion efficiency of the LED chip that produces green (G) light is currently low, and the electro-optic efficiency of the LED that produces blue (B) light is the highest. 1. The electro-optic efficiency of LEDs that produce red (R) light is in the middle; while the spectral components of white light are green light the highest, red light the second, and blue light the least. In order to adjust the white balance, the system will inevitably reduce the output power of blue and red light when combining light , which results in low white light efficiency, the greater the output power of the light source, the smaller the white light efficiency.

Summary of the invention The technical problem to be solved by the present invention is to propose a stage lighting system and its method to improve the output efficiency of high-brightness white light while increasing the light output power.

In order to solve the above-mentioned technical problems, the basic idea of the present invention is: since the brightness or efficiency of white light synthesis by using R, G and B three primary color LEDs is low, if the stage lighting system provides white light output during the period, it is set to use a single Color light is used to excite light wavelength conversion materials, such as phosphors, to produce white light, which can undoubtedly improve the brightness of white light.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Below, the present invention will be further described in conjunction with the preferred embodiments shown in the accompanying drawings.

According to the prior art, the method for providing various colored lights by the stage lighting system includes steps:

Aggregate the light from multiple LED chips in the LED array packaged on the heat dissipation substrate into a beam of combined light;

directing the beam of combined light to a light outlet;

The LED chips with different light emitting wavelengths in the LED array are controlled to emit light so that the light at the light outlet has a predetermined color or color change.

The inventive method is based on above-mentioned each steps, also comprises step:

During the time period when the light at the light outlet is white light, the LED chip with a predetermined wavelength is controlled to emit light, and at the same time, a transmission-type light wavelength conversion device is cut into the guiding light path of the combined light to generate stimulated light with a second predetermined wavelength. , to mix and generate white light; after this period of time, the transmission-type optical wavelength conversion device is cut off from the guiding light path.

As shown in Figure 1, the stage lighting lighting system designed according to the method of the present invention includes at least one LED array, which is composed of a plurality of LED chips packaged on the heat dissipation substrate at certain spatial intervals; The emitted light converges into a beam of combined light; the focusing lens 5 focuses the combined light to the light outlet 11 . Each LED chip on the same LED array can be made to be an LED of the same color. Figure 1 takes three LED arrays 1, 2, and 3 as an example, such as but not limited to using R, G, and B LED light-emitting chips respectively. Correspondingly, the light combining device 4 includes a light splitting and color combining device with three light entrance ports, and three lens arrays including a plurality of lenses corresponding to the LED array, each of which is aimed at an LED The chip collects the large-angle light output from the LED chip to the maximum, and converts the large-angle light into a near-parallel light with a certain divergence angle. The smaller the divergence angle of the near-parallel light, the better; from the three lens arrays The three beams (R, G, B) of near-parallel light beams are converged into one beam by the light-splitting and color-synthesizing device and directed to the focusing lens 5 . The light-splitting and color-combining device can be an X-type color-combining filter device with three light entrance ports as shown in the figure, so that each of the light entrance ports is aligned with a lens array; A cascaded color combination filter device with color filters arranged in parallel. The color-combining filter can be a dichroic film, or a glass plate coated with a light-splitting filter film; these are all involved in the relevant prior applications of our company, and will not be repeated here.

In fact, in occasions where the color requirements for the stage lighting system are not very rich, it may be sufficient to use two single-color LED arrays. Correspondingly, at this time, the light combining device 4 can be replaced by a color combining filter and two described lens arrays, and the two beams of near-parallel lights from the two lens arrays are directed to the described color combining filter one by one. The two sides of the light sheet are respectively converged into a beam by means of transmission and reflection and directed to the focusing lens 5 . In occasions where the brightness or color uniformity of the light emitted by the stage lighting system is not high, it is also possible to use only one LED array to simultaneously include two or more LED chips with different light emitting wavelengths. The light combination device 4 A light collection assembly with a cup-shaped reflective surface is used instead, the LED array is placed at the bottom of the cup of the light collection assembly, and the mouth of the cup faces the focusing lens 5 . Because these are not the focus of the present invention, no additional illustrations will be added.

The stage lighting lighting system of the present invention also includes a transmission-type optical wavelength conversion device 7, and a control processing device; the control processing device controls the light emission of each of the LED chips, and also controls the transmission-type optical wavelength conversion device 7 to switch in and out in a timely manner. The light path between the focusing lens and the light outlet. FIG. 1 illustrates the situation when the transmission-type optical wavelength conversion device 7 is cut into the optical path to generate high-brightness white light; FIG. 2 illustrates the situation when the transmission-type optical wavelength conversion device 7 is cut off from the optical path.

The transmission-type light wavelength conversion device 7 includes a light wavelength conversion material and a light-transmitting medium carrying or clamping the light wavelength conversion material. As shown in Figure 3, two light-transmitting media 15, 17 can be used to clamp the light wavelength conversion material 16, such as but not limited to phosphors, dyes or quantum luminescent materials; the light wavelength conversion material can also be mixed with glue Glue on any of the light-transmitting media.

The transmission-type optical wavelength conversion device 7 schematically shown in FIG. 1 is arranged on a light-transmitting wheel or a light-transmitting disc 9 with a rotating shaft 10, and the control processing device is controlled by controlling the rotation angle of the light-transmitting wheel/disk 9 The transmission type optical wavelength conversion device 7 is cut in or out in the optical path. The light wavelength conversion material is phosphor powder as an example, because after the small-angle incident excitation light passes through the phosphor powder, the emitted light exhibits a 180-degree Lambertian distribution, which makes the etendue of the system larger, which is not conducive to the light output port 11 for large-angle light. Collection and utilization; the stage lighting lighting system of the present invention also includes two linked lenses 6, 8, which cut into and out of the optical path along with the transmission-type light wavelength conversion device 7. The linkage lenses 6 and 8 can be convex lenses or thinner Fresnel lenses; in the optical path, the two lenses are placed on both sides of the transmission-type optical wavelength conversion device. The first lens 6 has a strong focusing ability, and the light is focused on the light wavelength conversion device 7; the second lens 8 collects the large-angle light from the light wavelength conversion device 7, so that the effective aperture of the outgoing light is consistent with the light outlet 11 Matched to reduce the loss of light energy.

Let each LED chip on one of the LED arrays in the system shown in Figure 1 be a blue LED chip, and the corresponding transmission-type light wavelength conversion device includes a light wavelength conversion material that can generate yellow stimulated light, then when the stage lighting is to project When the light is white, the control processing device controls the blue chip to emit light, turns off the LED chips on the other two LED arrays, and controls the linkage lenses 6, 8 and the transmissive light wavelength conversion device 7 to cut into the optical path. At this time, the fluorescent powder is excited to emit yellow light, and the yellow light and the blue light in the transmitted part are synthesized into white light, and the brightness efficiency is much higher than that of using R, G, B three primary colors high-power LEDs to synthesize white light. The different thickness of the light wavelength conversion material will affect the color temperature of the synthesized white light; therefore, the color temperature of the white light can be changed by adjusting the thickness of the light wavelength conversion material.

The linked lenses 6 and 8 can be designed to be linked with the transmission-type optical wavelength conversion device 7 , for example, to rotate around the rotation axis 10 together. In FIG. 2 , the linked lenses 6 and 8 are cut off from the optical path together with the transmission-type optical wavelength conversion device 7 , so that various color lights can be synthesized by using R, G, and B tricolor high-power LEDs. Adopting the switching scheme of the present invention can not only make up for the shortage of white light brightness in the existing LED stage lights, but also maintain the advantages of high color saturation and rich colors of the stage lights.

Considering that the light entering the transmission-type optical wavelength conversion device 7 may have relatively large optical power, in order to protect the optical wavelength conversion material, the transmission-type optical wavelength conversion device 7 can be converted into a light-transmitting wheel with a rotating shaft To carry or hold the optical wavelength conversion material. Correspondingly, the method of the present invention is improved as follows: when the transmission-type light wavelength conversion device is cut into the optical path, the rotation of the light-transmitting wheel is controlled so that a predetermined circular area on the light-transmitting wheel (carrying light in this area) wavelength conversion material) cyclically sweeps the optical path. In this way, heat accumulation on the light wavelength conversion material can be avoided at any place. Correspondingly, the cut-in or cut-out of the transmission-type light wavelength conversion device 7 in the optical path will be realized by moving the light-transmissive wheel by a moving mechanism. The linked lenses 6 and 8 can be linked with the transmission-type optical wavelength conversion device 7 through the moving mechanism, but not linked with the rotation of the wheel of the transmission-type optical wavelength conversion device 7 .

Considering the requirements of the pattern projection of the system of the present invention, the system of the present invention also includes a pattern wheel carrying one or more pattern sheets. As shown in Figure 2, when the transmission-type optical wavelength conversion device 7 is cut off from the optical path (the dotted line in the figure indicates the light-transmitting part cut in at this time), a pattern sheet can be set at the light outlet 11 . The gobo wheel can be a turntable 13 with a rotating shaft 14 as shown in FIG. But not limited to 131 ) is facing the light outlet 11 .

In this embodiment, when the gobo sheet 131 is fixed on the gobo wheel 13, it can also be designed to be able to rotate around its own axis, so that the system light pattern has a more dynamic effect.

If the system does not need to provide any patterns at the same time when providing white light, it can also be considered that one or more than one light transmission wheel/disk 9 shown in Figure 1 is provided on the area other than the transmission type light wavelength conversion device 7. The gobo, by controlling the rotation angle of the light-transmitting wheel/disc, it is selected whether the transmission-type optical wavelength conversion device or a certain gobo is cut into the optical path; as shown in Fig. 5a and Fig. 5b. In this solution, as shown in FIG. 5 a , due to the requirement of controlling the aperture of the participating imaging system, the second linkage lens 8 has higher specification requirements.

The system of the present invention may further include a projection lens 12 arranged at the rear end of the light outlet to guide the output light of the light outlet for long-distance projection.

The pattern sheet can also be without any pattern for use when generating white light or when required. However, it does not rule out that when the system provides white light, there is a demand for patterned sheets. Then the system structure can be partially schematically shown in Fig. 4 . The transmissive light conversion device 7 is set on the turntable 9 , and the gobo piece is set on the gobo wheel 13 . As shown in Figure 4a, when the transmission-type light conversion device 7 is cut into the optical path, in order to make the image clear, the projection lens 12 as a whole will move away from the light source; as Figure 4b, when the transmission-type light conversion device 7 is cut away from the When describing the light path, generally the gobo has a relatively large outer diameter. In order to make the imaging clear, the projection lens 12 as a whole should move toward the direction close to the light source.
